KEF LSX II LT Wireless Powered Hi-Fi Bookshelf Speakers


LSX II LT features the identical 11th generation Uni-Q driver array as LSX II, functioning as a single point source to expand the ‘sweet spot’ and distribute sound uniformly. This ensures everyone in the room can revel in room-filling, immersive sound.

Thanks to the Digital Signal Processing (DSP) algorithms within the Music Integrity Engine®, as well as the Uni-Q driver array and W2 wireless platform, LSX II LT delivers a meticulously balanced, high-resolution sound.

The two-speaker box approach also allows music to develop and breathe in a space, generating a three-dimensional soundstage. The speakers appear to disappear, leaving you to become fully immersed and drawn into the experience.


LSX II LT incorporates the same cutting-edge W2 wireless platform that drives LSX II, making music streaming effortless and always ensuring audio excellence, whatever you most love to listen to.

The latest KEF Connect app provides instant control over the speakers from the palm of your hand. Once the speakers have been unboxed, the app offers an intuitive on-boarding process to ensure a simple set-up. Easy connection for streaming, control and settings gives you the ability to personalise your audio and adjust the LSX II LT to best suit your home.

Plug and play to TV, desktop and more

With LSX II LT, you can connect your TV with HDMI ARC, your desktop or laptop with USB-C, and game console with optical. If you demand your movies and music come with extra bass, there’s a dedicated output to connect a KEF subwoofer.
